Do They Want To Support It Anymore?
I used to be inclined to agree with you regarding AVG, but presently it appears that they are attempting to phase out support for this software. (The Free Version)
It seems to be almost impossible to connect with their update service to get an update through the software.
If you go to their site to get a download, the download speed is so poor that it's possible to get disconnected during the download.
Try to discuss this situation with them presently and they become rather rude.
Free or not, anti-virus software that provides updates very infrequently or appears to perhaps not want to provide them at all is more dangerous than having none at all, as it only provides a false sense of security.
I'll stick with fprot, which also allows me to work in DOS if I suspect something has gone wrong, and that's great as many viruses and other demons do their dirty work before your system gets a chance to load.
